XRF Test Results For Oster Blender Milkshake Blade

Oster Blender Milkshake Blade

This item consists of one “component” (it cannot be taken apart without destroying it) made of three distinct materials:

1. The main silver colored metal of the blades (stainless).
2. The silver colored metal of the top nut holding the blade assembly together.
3. The copper colored metal at the base.

As I would have anticipated with an item like this (newly manufactured, primarily stainless steel) all components were negative for Lead (Pb), Cadmium (Cd), Arsenic (As), and Mercury (Hg).

Below are the full XRF readings for each metal in this item (when tested using “Consumer Goods” mode). For each of the components tested multiple tests were done to confirm the levels (for 30 seconds or one minute per test). For any element/metal detected, levels below 90 ppm are generally considered “trace” and not an additive to the product.:

NOTE: XRF testing is recognized by the Consumer Product Safety Commission as an acceptable and accurate way to screen consumer goods for potential toxicants. The Niton XL3T model that I use tests down to single digit parts per million for any metals detected. I am not a lab (and do not represent a lab or work with a lab) and, as such, no formal reports (other than the results as shared in these blog posts) are created through my work. That said the results are accurate (within the limitations of the testing methodology) and fully replicable by others using the same instrumentation (and also generally by others using digestive or destructive testing as long as the components are tested separately.)

Thank you for reading my posts and for sharing!

As always, please let me know if you have any questions.
